CYLINDER OR ROLLER FOR CARDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 241,051, dated. May 3, 1881.

Application filed Novembcrffl, 1880. (No model.)

To all whom it may concern Be it known that I, HAMILTON L. MOULTON, a citizen of the United States, residing in Camden, New Jersey, have invented certain Im- 5 provemeuts in Uylinders or Rollers for Garding-Machines,of which the following isa speci fication.

The object of my invention is the secure attachment ot' card-clothing to the metal cylin- 1o ders and rollers of cardin g-machines-au object attained by embedding in the iron cylinders pieces of lead or soft alloy,into which the tacks are driven through the leather, or rubber, or other base of the card-clothin g.

1 In the accompanying drawings, Figure 1 is a section of apart of the main cylinder of a carding-engine, showing the inlaid plugs of lead,into which the tacks for securingthe cardclothing are driven; and Figs. 2 and 3, views 20 illustrating; a mode of introducing the leaden plugs into the orifices or recesses in the cylinder.

The main cylinders of carding-machines are generally made of wooden slats secured to castiron centers, the card clothing being secured 25 to the wood by tacks. The objection to this class of card-cylinders is their liability to get out of truth, owing to the warping of the wood.

Card-cylinders are sometimes made of castiron, the circumference being turned perfectly 3o true, and holes being made in the cylinder for the reception of wooden plugs, into which the tacks for securingthecard-clothing are driven; but these plugs are apt to shrink and become loose in the holes into which they have been 5 driven, and the consequence of this is the loosening of the card-clothing.

In order to obviate this difficulty I drill into the cylinder A, at suitable intervals, holes a, into which I drive plugs b, of lead, the super- 40 fluous portion of each of which is cut off flush with the surface of the cylinder. The cardclothing D is applied to the cylinder in the usual manner, and the toothless portions of the .strips of clothing are secured by tacks driven into the lead, as shown in Fig. 1. I prefer to so drill the holes in the cylinder that the point only of the drill will pass through the same, as shown in Fig. 2; but simple recesses may be drilled or otherwise formed in the cylinder, as shown in Fig. 3, for the reception of the plugs; but it is immaterial how the holes or recesses are made, or how the lead is introduced into the same, providing that metal, or a soft alloy of which lead forms a part, is embedded in the cylinder a-tintervals, for receiving the tacks which secure the card-clothin g to the cylinder. The tacks, after being driven into the lead, are effectually retained by the same, and as the lead cannot shrink, my invention results in a card-cylinder which retains its truth, and to which the card-clothing is so firmly secured that it is not liable to become detached through accident or during the working of the machine.

I claim as my invention 1. An iron card cylinder or roller in which lead or soft alloy is embedded at intervals, sub stantially as set forth.

2. The combination of an iron card-cylinder or card-roller, having inlaid pieces of lead or soft alloy, with card-clothin g secured to the cylinder by tacks driven into the lead, as specified.

In testimony whereof I have signed my name to thisspecitication in the presence of two subscribing witnesses.
